Canada Lynx The Canada lynx (Lynx cmrndensis), is a medium-sized cat with long leers, well furred paws, long tufts on the ears, and a short black tipped tail. Adult males average 22 pounds and thirty- three inches in length head to tail. Adult females average nineteen pounds and measure thirty- two inches in length. Suitable habitat includes primary habitat of coniferous forests of spruce and Fr or lodgepole pine, and secondary habitat of aspen or Douglas-fir mixed with the primary habitat at elevations between 8,000 and 11,500 feet. Lynx also periodicafly traverse other forested and non-forested habitats including lower elevation woodlands and shrublands. Suitable or potentially suitable habitat that would support lynx, based on existing vegetation, does not exist on the Roadside North and South Portals permit area. Due to a lack of suitable habitat, OSM has determined that a PR-03 will "not affect" the continued existence of the Canada]ynx. Southwestern Willow Flycatcher The southwestern willow flycatcher, (Empidonnz traillii extimtrs), is a bird with agrayish-green back and wings, whitish throat, light olive gray breast and pale yellowish belly. Two wing bars are visible, eye ring faint or absent. This migratory species occupies riparian breeding habitat from late April to September at elevations at less than 8,500 feet above mean sea level. Suitable habitat consists of riparian habitats along rivers and streams, or other wetlands where dense growths of willows, arrowweed, buttonbush, tamarisk, with a scattered over story of cottonwood. Suitable or potentially suitable habitat for the southwestern willow flycatchers does exist along the Colorado River. However, this habitat does not exist on or adjacent to the previously disturbed area covered by PR-03. Therefore, OSM has determined that PR-03 will "not affect" the continued existence of the southwestern willow flycatcher. Uinta basin hookless cactus The Uinta basin hookless cactus (Sclerocacrats glaucus) is a commonly solitary, egg-shaped, three to twelve centimeters long stem that produces pink flowers late from April to late May. The Uinta Basin hookless cactus is known from eight sites in a five county area of eastern Utah and western Colorado and is found on alluvial deposits of the Colorado Plateau overlain with cobbles and pebbles, at elevations ranging from 4,500 to 6,600 feet. Baseline surveys for the Uinta basin hookless cactus were conducted in both 198?, 1983 and again in 1996. While theses surveys concluded that the Uinta basin hookless cactus had the potential to occur on the Roadside North and South Portals permit area, none were observed. Suitable or potentially suitable habitat does not exist, however, on the previously disturbed area covered by PR-03. "Therefore, OSM has determined that PR-03 will "not affect" the continued existence of the Uinta basin hookless cactus.
